Prior to version 1.5.16, the default Rsdoctor report HTTP server started by `@rsdoctor/rspack-plugin` binds to all network interfaces (`0.0.0.0`) and serves a `POST /api/data/key` endpoint with no authentication and wildcard CORS (`Access-Control-Allow-Origin: *`). Any network-adjacent or remote attacker can send a single unauthenticated request to retrieve the full source code of all compiled JavaScript modules (`moduleCodeMap`), serialized build configuration (`configs`), error details, and other sensitive build metadata. This server is enabled by default in non-CI environments, requiring no special configuration from the victim developer. Version 1.5.16 patches the issue.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-61782)\n\nAffected packages:\n\n- `@rsdoctor/rspack-plugin <= 1.5.15`\n\nPatched in:\n\n- `@rsdoctor/rspack-plugin 1.5.16`\n\nSource: https://github.com/advisories/GHSA-jmg2-rcxh-w8q3","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
